The xdaliclock program displays a digital clock, with digits that merge
into the new digits as the time changes. Xdaliclock can display the time
in 12 or 24 hour modes and can will display the date if you hold your
mouse button down over it. Xdaliclock has two large fonts built in, but
is capable of animating other fonts.
Install the xdaliclock package if you want a fairly large clock, with
a melting special effect, for your system.
